You guys are still getting bad checksums?
Yeah, I am.
Oh, sorry, all the other bugs gave me a head-fake, and I forgot the
original problem of -fsck- corrupting the checksums. :) I had a simple
mkdir giving me the corruptions. Ok, on to that.
I found the source of the checksum error last night - the reserved bytes
in the 64-bit group descriptor are not zero after the e2fsck is run.
It should be pretty easy to run e2fsck under gdb and put a hardware watch
on those bytes to see who twiddles them.
Thanks, I saw that email a bit late today, will take a look.
